HOSE-CLAMP TOOL.

Specification of Letters Patent.

Application filed September 21,-1918. Serial No. 255,183.

To all whom it may concern. I

Be it known that I, BERNHARDT HENRIE- SON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hose-Clamp Tools, of which the following is a specification.

My invention has for its object to produce with parts in elevation.

To secure a couplin element a in the end of a garden hose 6, y an outside tie-wire 0 or to apply a looped or hair-pin tie wire tightly around any object of small circumference, the ends of wire-limbs 0 may be passed through the bend 0 tension being then applied to draw the limbs through the loop until the encircling strands are taut, and ,then the limbs may be bent sharply back as shownin dotted lines, Fig. 1, cut off, and hammered down as hooks closely gripping the wire-bend 0 It is to facilitate such operations that the tool is employed.

A frame-memberG carries both active elements of the tool, namely a clamp structure 7 for engaging the tie-limbs c and a traveling presser-head structure 8, for engaging and moving the. wire-bend c Specifically clamp structure 7 provides a handle or lever 9 operating a movable clamp jaw 10 in suitable fashion'to grip the wire-limbs against a.

fixed-jaw portion or anvil surface 11 of the frame. Th 'e frame has bottom lugs 12 supporting pivot 13 for lever 9, and the jaw 10 has an eccentric end 14, toothed at 15, to close against fixed jaw 11 as handle 9 is moved rearwardly. The presser head proper," 16, is a part shapedfor engagement with the wire-bend 0 its tapered, rounded nose 17 havin for this purpose a transverse groove 18. his head is mounted on the frame forlinear movement without rotation, being arranged to have its movement guided by the frame and occasioned by pressure applied against the frame. Thus an offset 19 at the base of the head rigidly engages a guide bar that slides through an opening 21 in the frame, just above the anvil-surface 11, and that acts both to guide the head and prevent its rotation. The head is swiveled on the end of a screw-stem 22 that has thread engagement with the opening 23 in the top portion of the frame, and that, in rear of the frame, has an operating handle or wing-head 24. This screw obviously will propel the head axially. The slide-bar preferably extends nearly to the hub of the screw-handle 24 so that the bar may not lose engagement withthe frame when the stem 22 is screwed clear forward, and for knock down purposes the head 16 is mounted detachably on the screw stem.

Specifically, the forward end of stem 22 is smooth and grooved as at 26, to fit in a recess 27 in the head, a removable keeperscrew 28 taking ,into the groove to hold the parts assembled.

In operation, when the hairpin wire has been looped around the hose, with its limbs projecting beyond bend 0 the tool, with its head 16 suitably retracted, has its clamp jaws opened andis slipped over the wire limbs until the groove 18 in the pressure Patented July 27, 1920. I

head engages the bend of the wire; Then one closes the clamp to grip both wire-limbs and turns the screw-wings to push the pressure head forward. 7 Of course the stronger the screw pressure the tighter clamp 7 holds since the strain on limbs 0. tends to tighten Y the eccentric clamp and so with great easeholding handle 9 in one hand and working the screw-stem with the otherone may draw the encircling wires perfectly taut. The

shape of the pressure-head, 16, its accurate guidance by the screw 22 and bar 12, and the fact that its endtravels along between the limbs 0 of the wire, all aid to insure perfect and uniform operation. When the tie is tight enough one merely rotates the tool bodily around the wire-bend as a fulcrum, by pressure on lever 9, so that the wire limbs are hooked around the bend a without the slightest liability to slippage. The tool is then detached by releasing the clamp and withdrawing the device, leaving the wire ends free to be cut oif and pounded down in any convenient way.

. It-will be understood that while I have herein described in some detail a specific embodiment of my invention many changes in construction and details of arrangement may be made without departure from the spirit of my invention within the scope of the appended claims.

I claim: 1. A tool of the character described comprising a head having a transverse groovev to coact with the bend of a hairpin-wire, a

screw-stem making rotatable but axiallya fixed connection with the head and having a turn-handle, a slide rod paralleling the screw-stem and fixed to the head, a transverse frame member making threaded engagement with the screw stem and engag ing the slide rod to be held thereby against rotation, and a single clamp jaw pivoted to said frame having provision for gripping both'strands of a hairpin-wire and having a lever extending outwardly substantially at right angles to the stem, when in clamping position, and pivoted with its axis substantially parallel to the head-groove, whereby said lever acts as a handle by which the tool may be swung about said head as a fulcrum.

2. A tool of the character described comprising a head transversely grooved to 00- act with the bend of a hairpin-wire, a screwstem making rotatable but axially-fixed connection with the head and having a turnhandle, a slide rod paralleling the screwstem' and fixed to the head a transverse frame I member making threaded engage- 'ment with the screw stem and apertured to receive the slide rod, and a single clamp jaw pivoted tosaid frame beyond the slide rod on an axis paralleling the head-groove and having provision for gripping both strands of a hairpin-wlreincluding a lever extending outwardly substantially at right angles to the stem-when in clampin position and acting to clamp when pul ed toward the turn-handle of the stem; whereby said lever acts as a handle by which the tool may be bodily'swung upon the head as a fulcrum.

3. In a hose banding tool, the combination of a short transverseframe having in vertical alinement a threaded orifice, a smooth orifice and a stationary clamp jaw, a threaded stem: extending through said threaded orifice'and having at one end a turn-handle, a head swiveled on the other end of said stem and having a cross-grooved screw extending through said screw open-' ing and having an operating handle, a resser-head swiveled on said screw and having a cross-grooved nose, and a bar carried by said presser head and guided in the of the character described,-

frame to "prevent head-rotation, said clamp lever being disposed to stand at substantial right angles to the screw when 'in clamping position, whereby it serves as a single handle for swinging the tool about the grooved nose of the-head as-a fulcrum.
